That's not a paradox though, it's a silly logic puzzle that isn't hard to solve. It doesn't prove or disprove anything about omniscience or gods.

It is a paradox if you believe there are omniscient beings. If there are no omniscient beings, there is no paradox. The sentence is either true or false. If the sentence is true, we have an omniscient being that lacks knowledge about a true statement. Contradiction. If it is false, there is an omniscient being that knows it to be true. This means that the statement is true, but the statement itself says that no omniscient being knows it to be true. Contradiction.

It's not a paradox, it's a dumb logic puzzle. It's no different than saying something nonsensical like "This sentence contains 2 words".

If it is false, there is an omniscient being that knows it to be true

No, if it is false, then it is simply wrong. A wrong sentence doesn't imply something else is right, it's just wrong.

"This sentence contains 2 words" is a sensible sentence. It has 5 words, so what the sentence says is false.

The self-reference in the sentence is similar to that of the Liar's paradox. Cousins of that paradox have been used to prove major limitative results in mathematical logic such as

https://en.wikipedia.org/wiki/Tarski%27s_undefinability_theorem

https://en.wikipedia.org/wiki/Gödel%27s_incompleteness_theorems

In usual logic, a false sentence implies every sentence.

Also, if sentence P is false, then "P is false" is true

I'm sure the official line would be that God is also ineffable to man. "omniscience" as some human has expressed it in whatever flawed language it is probably a flawed translation from ineffable divine meaning.

Where is the evidence that god is actually "omniscient" or caims to be in the way that this proof interprets the term? It seems like hearsay to me.

But irrespective of what this god-thing may or may not have said about itself to whom, I don't see how the statement does more than show that "'omniscience' is a poorly defined/illogical term". Or maybe, "People who use the word 'omniscience' to describe the extent of knowledge are not expressing themselves clearly or accurately".

This should not be all that surprising as most humans - as I understand them - rarely need to communicate clearly about infinites - so those that do should probably not use English and choose a more apposite language. Maybe hebrew or watever languages these supposed prophets might have used has better terminology.

I suspect Moses might have flunked maths.
